monomier=a molecule that can be bonded to other identical molecules to form a polymer.

polymer=a substance which has a molecular structure built up chiefly or completely from a large number of similar units bonded together, e.g. many synthetic organic materials used as plastics and resins.

ans 4=Rayon is a man-made fibre prepared from a natural raw material called cellulose by chemical treatment. The cellulose required for making rayon is obtained from wood pulp. Rayon is obtained by the chemical treatment of wood pulp. 1)Wood pulp is dissolved in an alkaline solution to form sticky liquid called viscose

ans 5=Nylon is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variation
